2.5 to 2.8 gns max charge for 148 gn wad cutter at 815 fps. I would pull them as mentioned. If you notice Bullseye does not give alot of room for margain in thier load data. It seem to be a few points of a gn from start to max in thier loading data.
Given that, for the 357 magnum it calls for 5.1 to 5.7 max. of bullseye. Your 4.0 is niether here nor thier, I wouldnt chance it myself. Can it become a squib load for the 357, being loaded that low? Probably not, but why chance it.
I have a big coffee can under my reload bench for such things, one day i have a whole lot of pulling to do also.
Hey, it happens to the best of us. Best that you caught it.
stay safe Jack
